v1.3.2

Fixed

• Activating the plugin after a Composer install fataled the site. The
  bootstrap required vendor/autoload.php unconditionally, and that directory
  exists only in the release zip: installed as a Composer package the file is
  absent, so activation ended in a fatal error and the site answered 500. The
  autoloader is now required only when it is there — a Composer install already
  has the package's PSR-4 mapping in the consuming project's autoloader. If
  neither source produced the classes the dashboard says so instead of fataling.
